Injuries could force Cowboys to re-shuffle offensive line

With starting center Phil Costa out with an ankle injury and backup Ryan Cook doubtful with an injured knee, the Dallas Cowboys likely will be forced to re-shuffle their offensive line Sunday against Cleveland.

If Cook can’t play after missing every practice this week, right guard Mackenzy Bernadeau would make his first career start at center and veteran backup Derrick Dockery would line up at right guard.

“I always embrace the challenge,” Bernadeau told ESPNDallas.com. “Even though I haven’t played center in a game, I’ve done it in the preseason and it’s something I’m confident with. It’s new, so it’s exciting.”

Bernadeau took most of the snaps at center with the first team this week. Kevin Kowalski also took snaps with Tony Romo, but he remains inactive.

Bernadeau said the changes shouldn’t hurt the line’s chemistry.

“That’s what practice is for,” Bernadeau said. “I thought we (him and Dockery) did well I for the first time being in there together. It went well.”

Running back DeMarco Murray didn’t practice this week, but the Cowboys upgraded him to doubtful after he missed the last four games with a sprained left foot. Although the upgrade is a sign of progress, it would be a big surprise to see Murray active.

The Browns’ lengthy injury report includes a notable defensive starter: cornerback Joe Haden, who is questionable after missing the last two practices with a pulled oblique muscle. He likely will be a game-time decision.
